The Graco 17J871 Kit, Tube, Suction, Prox21 is engineered to deliver consistent performance when tackling large coating jobs. Designed for the ProX21 cart system, this premium accessory ensures optimal material pick-up while keeping contaminants at bay. Pair it with your airless sprayer to maintain smooth flow and uninterrupted output, making every coat flawless. This genuine Graco part meets industry standards for reliability and precision control.
Ideal for professional coatings jobs, the Graco 17J871 suction tube kit integrates a high-flow filter screen to trap debris before it reaches your pump, reducing wear and tear. Compatibility with a broad range of fluids—from latex to heavy epoxies—makes it a versatile addition for contractors. Upgrade your equipment with a component that balances flow efficiency and durability through its advanced high-pressure filtration design.
Featuring advanced suction performance and engineered for consistent material delivery, this tube assembly elevates daily operations within high-demand painting and coating environments. Its streamlined path reduces clogging potential while maintaining optimal viscosities. Whether moving heavy coatings or light sealers, operators can expect uniform draw rates. Precision machining ensures each tube segment aligns flawlessly with the ProX21 fluid section.
A modular architecture simplifies installation and future servicing. Experienced technicians rely on graco replacement parts to keep their equipment running smoothly, minimizing downtime between projects. Compatibility extends to multiple inlet configurations, enabling direct mounting into various manifolds and adaptor plates. Compact dimensions save space in tight setups without sacrificing flow capacity, supporting both low- and high-viscosity fluids with equal effectiveness. Tolerance limits maintain concentricity within 0.1 mm, ensuring uniform seal engagement. Calibration marks on the inlet lip serve as visual guides for correct seating depth. Pilot fitting reduces risk of cross-threading or misalignment during high-pressure deployments. Manufacturing quality checks include pressure testing at 3000 PSI to verify leak-free operation before shipping.
Precision-welded joints and corrosion-resistant alloys form the foundation of this suction tube’s robust frame. Performance remains reliable even in abrasive or solvent-heavy conditions, thanks to careful material selection and finishing processes. Compatibility even extends to some graco magnum paint sprayer setups when paired with adapters designed for cross-model interchange. Overall integrity ensures years of service under continuous cycling and pressure variations. Heat-treated stainless steel resistors and FDA-approved elastomer seals deliver chemical resistance for solvent-based or waterborne coatings. Surface treatments include passivation and electropolishing, helping reduce corrosion hotspots. Weld joints comply with ASME standards and undergo ultrasonic inspection to detect microfractures. Endurance testing simulates one million pump cycles to validate long-term reliability under fluctuating temperatures and pressures.
Engineered clearances within the tube maintain laminar flow, limiting turbulence and preserving coating composition. Optimized internal diameters prevent buildup while reducing shear stress on sensitive media. Hydraulic modeling influenced the design, resulting in balanced velocity profiles across a range of fluid viscosities. Performance testers noted up to 15 % reduction in material waste compared to legacy suction assemblies, translating to cost savings in large-scale operations. Advanced computational fluid dynamics simulations guided the contouring of bends, minimizing energy loss across the entire length. Pressure drop is calibrated to remain under 5 % of supply pressure, optimizing pump loading. Continuous-flow bench tests demonstrate stable output even when switching between high- and low-viscosity media within seconds. Field studies confirm up to 20 % improvement in finish quality due to reduced pulsation.
Proper alignment is crucial for smooth operation. Always examine mating surfaces for debris before seating the tube to prevent seal damage. Lubricate O-rings sparingly with compatible grease and install retaining clamps securely to avoid vibration-induced loosening. Scheduled inspections at 250-hour intervals help detect wear patterns early, while gentle cleaning with non-abrasive brushes extends service life. Protective caps should remain on unused ports to block contaminants. Incorporating a torque wrench with a 0.5 Nm setting helps avoid over-tightening hose clamps. Replacement of the primary O-ring after 1000 cycles is recommended. Use non-silicone based lubricants for seal conditioning prior to reassembly to prevent swelling or degradation. Store spare tubes in a clean, dry environment and inspect packing materials during service to ensure compliance with ISO cleanliness standards. Detailed exploded diagrams facilitate parts identification.
Automotive refinish shops utilize this kit to streamline basecoat and clearcoat operations, while marine coatings specialists appreciate its resistance to epoxies and antifouling compounds. Industrial maintenance crews depend on quick-change capabilities to switch between abrasive primers without mixing cross-contamination. Research laboratories employ the suction tube for precise dispensing during material development or rheology analysis. Standardized fittings promote interoperability with various accessory modules, reducing training time and simplifying supply chain management. Field service teams benefit from rapid part swaps during critical changeovers, ensuring production lines maintain optimal uptime. Laboratory technicians value predictable flow rates when testing novel formulations at different scales.
Quality assurance teams value traceability features that record batch numbers and manufacturing dates etched on each component. Integrating the tube within preventive maintenance schedules aids lifecycle management and reduces emergency repairs. Technical support teams provide documentation and on-site consultation to optimize system architecture according to specific project demands. Regular audits of fluid delivery modules ensure compliance with industry regulations and safeguard operational consistency. Consider pairing this assembly with a dedicated graco paint sprayer pump repair kit for comprehensive upkeep and peak performance throughout every project phase.
